Based says some KYC data was exposed, while Visa card funds remain unaffected
Web3 financial platform Based said it discovered on Oct. 5, 2026 that an unauthorized third party had breached an internal panel used to manage its Based Visa card program. After reviewing the incident, the company said some cardholder KYC data collected by the card issuer may have been accessed, including names, ID document numbers, dates of birth, and addresses. Based added that card numbers, CVV codes, PINs, transaction wallets, and funds stored on the cards were not affected, and that normal Visa card spending continues to operate. The company said it has notified affected users and reported the matter to regulators. It also warned users to stay alert for impersonation attempts and phishing attacks.
